Types of Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves and electromagnetic waves.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through a vacuum and does not require a medium.

Front

Give an example of a mechanical wave.

Back

Sound waves and ocean waves are examples of mechanical waves.

Front

Give an example of an electromagnetic wave.

Back

Light waves, X-rays, and radio waves are examples of electromagnetic waves.

Front

How do sound waves travel through different media?

Back

Sound waves travel fastest in solids because molecules are closer together, allowing quicker energy transfer.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

Can electromagnetic waves travel through a vacuum?

Back

Yes, electromagnetic waves can travel through a vacuum.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases and vice versa.
